For the past fifty years, besides his necessary daily cultivation, he had been constantly modifying the *Martial Scripture* to perfectly suit his current stone body.
He had practiced the Martial Dao in the past, but his cultivation Realm was low back then, so he could get by without any modifications.
But now, as his Realm continued to grow, this matter had become increasingly crucial.
Fortunately, after all these years of observing the Martial Dao cultivation of the Divine Shadow Guard, Li Chang'an had made excellent progress.
He had personally established nine Realms for Martial Dao cultivation: Entering the Dao, Mastery, Minor Achievement, Great Success, Perfection, Ultimate Perfection, Grandmaster, Grandmaster, and Divinity Transformation.
He had now modified and perfected the *Martial Scripture* enough to allow him to cultivate to the Perfection Realm.
From the perspective of his long life, this rate of modification was already quite impressive.
